Context: We know one thing only. Absolute existence, absolute motion, absolute direction, absolute simultaneity, absolute truth, all such ideas: they have not, and never can have, any real meaning. If a man in delirium tremens fell into the Hudson River, he might remember the proverb and clutch at an imaginary straw. Words such as "truth" are like that straw. Confusion of thought is concealed, and its impotence denied, by the invention. This paragraph opened with "We know": yet, questioned, "we" make haste to deny the possibility of possessing, or even of defining, knowledge. What could be more certain to a parabola-philosopher that he could be approached in two ways, and two only? It would be indeed little less that the whole body of his knowledge, implied in the theory of his definition of himself, and confirmed by every single experience. He could receive impressions only be meeting A, or being caught up by B. Yet he would be wrong in an infinite number of ways. There are therefore Aleph-Zero possibilities that at any moment a man may find himself totally transformed. And it may be that our present dazzled bewilderment is due to our recognition of the existence of a new dimension of thought, which seems so "inscrutably infinite" and "absurd" and "immoral," etc. — because we have not studied it long enough to appreciate that its laws are identical with our own, though extended to new conceptions.

Context: Mountains should be climbed with as little effort as possible and without desire. The reality of your own nature should determine the speed. If you become restless, speed up. If you become winded, slow down. You climb the mountain in an equilibrium between restlessness and exhaustion. Then, when you are no longer thinking ahead, each footstep isn't just a means to an an end but a unique event in itself. This leaf has jagged edges. This rock looks loose. From this place the snow is less visible, even though closer. These are things you should notice anyway. To live only for some future goal is shallow. It’s the sides of the mountain that sustain life, not the top. Here's where things grow. <!-- p. 205

Letter to Mercy Warren (1789)
Context: I little thought, when the war was finished, that any circumstances could possibly have happened, which would call the General into public life again. I had anticipated that, from this moment, we should have been left to grow old, in solitude and tranquillity, together. That was, my dear madam, the first and dearest wish of my heart; but in that I have been disappointed. I will not, however, contemplate, with too much regret, disappointments that were inevitable. Though the General's feelings and my own were perfectly in unison, with respect to our predilection for private life, yet I cannot blame him, for having acted according to his ideas of duty, in obeying the voice of his country. The consciousness of having attempted to do all the good in his power, and the pleasure of finding his fellow-citizens so well satisfied with the disinterestedness of his conduct, will doubtless be some compensation for the great sacrifices, which I know he has made.
